N. de publicación: US 2011039018 A1

A silver conductive coating possessing infrared absorbing properties is disclosed. The coating is made from a blend of one or more micron size silver powders and/or flakes together with carbon black, inorganic pigment, glass frit, and powdered selenium or bismuth metal. The foregoing dry ingredients are pasted with an organic vehicle, applied to a substrate, and fired at a temperature of up to 1400 DEG F. The coating absorbs infrared radiation beyond the decomposition of carbon black, thus allowing higher firing temperatures and hence shorter firing times.
